Respuesta:
a. - 2a - 5
b. b + 14
c. x - 2
d. 2x + 7y
e. 8x + 5y
Explicación paso a paso:
a.
( 4a - 2 ) - ( 6a + 3 )
= 4a - 2 - 6a - 3
= 4a - 6a - 2 - 3
= - 2a - 5
b.
( 8b + 9 ) - ( 7b - 5 )
= 8b + 9 - 7b + 5
= 8b - 7b + 9 + 5
= b + 14
c.
( - 10 - 3x ) - ( - 4x - 8 )
= - 10 - 3x + 4x + 8
= 4x - 3x + 8 - 10
= x - 2
d.
( 3x + 2y ) - ( - 5y + x )
= 3x + 2y + 5y - x
= 3x - x + 2y + 5y
= 2x + 7y
e.
( 4x + 4y ) - ( - 4x - y )
= 4x + 4y + 4x + y
= 4x + 4x + 4y + y
= 8x + 5y
